SWCI Commands
SWCI Commands
SWCI executes each command as it is entered and displays results in the TACL window
from which SWCI was started (or to an alternate terminal or file if specified in the
TACL RUN command). SWCI continues to execute commands until it encounters either
an EXIT command or (if input is from a file) an end-of-file condition . Any invalid
command or other error condition detected by SWCI during command execution results
in an error message; but does not terminate SWCI. SWCI commands have a timeout
value of one second, except the SELFTEST command, which has a timeout value of
three seconds. For examples on using SWCI commands for planned and unplanned
outages, see Section 5, Switchovers
.
The SWCI commands are summarized in Table 6-1
, and are categorized into three types:
•
Action
•
Control
•
Status
